Autodesk MapGuide Enterprise SDF Reader Parameters

The path of the SDF3 file to be read.

Specifies whether to keep the table qualifier. The full name of a table in a database is of the format:

<prefix>.<table_name>

Depending on the database format, the prefix can be <database_name>.<owner_name>, <owner_name>, or <schema_name>.

Selecting this parameter indicates that the reader should return the table name without any prefixes. This is useful, for example, when creating a workspace that will be passed on to another organization using the same table names, or performing a translation to another database format but with a different user name.

When this parameter is selected during workspace generation, the source feature types will be the table names without any prefix; otherwise, they will contain the owner name as a prefix. It is recommended that you do not change this parameter after generating the workspace, because it is possible for no features to be successfully passed onto the writer (since the writer is expecting feature types with different names).

Note: Even when this parameter is selected, if the table is owned by a user other than the current user, the prefix will not be dropped. This is to ensure that the reader will find the correct table.

Click the Browse button to select feature classes for export.

Use this parameter to expose Format Attributes in Workbench when you create a workspace:

• In a dynamic scenario, it means these attributes can be passed to the output dataset at runtime.
• In a non-dynamic scenario where you have multiple feature types, it is convenient to expose additional attributes using this one parameter. For example, if you have ten feature types and want to expose the same attribute in each one, it is easier to define it once than it is to set each feature type individually in the workspace.

Using the minimum and maximum x and y parameters, define a bounding box that will be used to filter the input features. Only features that intersect with the bounding box are returned.

If all four coordinates of the search envelope are specified as 0, the search envelope will be disabled.

Select this parameter to remove any portions of imported features being read that are outside the Search Envelope.

The illustration below shows the results of the Search Envelope when Clip to Search Envelope is set to No on the left side and Yes on the right side.

• No: Any features that cross the search envelope boundary will be read, including the portion that lies outside of the boundary.
• Yes: Any features that cross the search envelope boundary will be clipped at the boundary, and only the portion that lies inside the boundary will be read. The underlying function for the Clip to Search Envelope function is an intersection; however, when Clip to Search Envelope is set to Yes, a clipping operation is also performed in addition to the intersection.
